Hello , there . How can I help ?   Hello . I'm hoping to buy some Treasury Certificates today . Are they available ?   Certainly , Visible Treasury Certificates . Then you can get a receipt from the savings office as proof of payment . Hence the ' visible ' , you can see it .   Ah , right . How much do I need to spend ?   The minimum is 100 RIB , and the maximum is 500,000 RIB .   How about Bearer Certificates ? Are they different ?   Yes , they are different because they are printed by the Ministry of Finance in set amounts . Just 100 RIB , 500 RIB and 1,000 RIB , you cannot choose from many amounts , you see .
